How NASA translates space data into sparkly and haunting songs

You’ve probably heard that if you scream in space, no one will hear a thing. Space is a vacuum, so sound waves don’t have anything to bounce off of. But that doesn’t necessarily mean that space is silent. A team of researchers are taking data from a variety of telescopes and assigning them sounds, creating song-length sonifications of beloved space structures like black holes, nebulas, galaxies, and beyond. The album, called “Universal Harmonies” aims to bring galaxies to life and allow more people, such as those who are blind and low-vision, to engage with outer space.Guest host Flora Lichtman talks with two of the scientists behind “Universal Harmonies,” Dr. Kimberly Arcand, visualization scientist at NASA’s Chandra X-ray Observatory, and  Dr. Matt Russo, astrophysicist and musician at the University of Toronto.Visit our website to listen to a selection of the ethereal sonifications of “Universal Harmonies.”Universe of Art is hosted and produced by D. Peterschmidt, who also wrote the music. Our show art was illustrated by Abelle Hayford. The original segment featured in this episode was produced by Science Friday producer Rasha Aridi.
